MACHINE FOR CUTTING SOLES FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 443,515, dated December 30, 1890.

Application filed August 25, 1890. Serial No. 362,973. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES A. GILMAN, of North Weare, in the county of I-Iillsborough, State of New Hampshire, have invented a cer- 5 tain new and useful Improvement in Machines for Cutting Soles for Boots or Shoes, of which the following is a description sufticiently full, clear, and exact to enable any person skilled in the art or science to which to said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of my improved 1 5 sole-cutting machine; Fig. 2, a vertical transverse section taken on line a; a: in Fig. 1; Fig. 3, a plan showing the pattern attached to the stock, and Fig. 4 a like view of the completed sole.

: Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates, especially, to machines for cutting or trimming boot or shoe 2 5 soles by pattern; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce asimple, cheap, and effective article of this character.

The nature of the improvement will be read- 0 ily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body of the machine, which consists of a standard provided with a vertically-arranged forked head I). A l1orizontally'arranged shaft d is journaled in the arms of said head and bears a driving-pulley f. On the outer end of said shaft a circular cutter-head g is secured, to the outer edge of which and slightly within the periphery thereof a series of curved cutting-blades h are secured by clamping-bolts '1 which pass longitudinally through said head. These knives are thus rendered adjustable longitudinally of themselves on the face of the cutter-head in relation to the periphery thereof, whereby the depth of the carving to be taken from the sole is regulated. A cap B is fitted to slide on said head g, the edge of said cap around its mouth being beveled outwardly at j. The cap B is adjustable longitudinally on the head g by means of a screw Asliding cutter-head C is splined onto the shaft cl between the fork b and head g. The head 0 is provided with a series of horizontally-arranged blades on, having their outer ends bent backward at an angle to their bodies in such manner that the line of their cutting-edges p are at an acute angle to the axis of the shaft. These blades are arranged sufficiently far from the shaft to ride over or inclose the head g, when their head 0 is forced outward. Said head 0 is grooved peripherally at q, and a collar '1' is fitted to rotate in said groove. Two horizontal rods 25 slide in lugs to on the fork band have an end secured in ears 1) on said collar. The outer ends of said rods are screw-threaded, and nuts 'y work thereon, forming stops for engaging the outer lugs to and determining the longitudinal movement of said rods in one direction. A lever .2, pivoted on the fork b, has one end pivoted to the outer ends of the rods tand its opposite end connected by a vertical rod 15 with a treadle 16 at the base of the standard A. The treadle mechanism described is designed to force the beveling-blades of the head 0 against the sole in manner hereinafter described. Below the head 0 an arm 17 projects from the fork b, and is provided in its outer end with a longitudinally-adjustable 8o angle-rod 18, which serves as a guide for the sole while being operated on by the blades h.

In the use of my improvement the pattern D is tacked to the stock E in the usual manner. The cap B is adjusted on the head 9 with its beveled edge j at a suitable distance from the inner edge of said head to enable the edgeo'f the pattern to bear thereon at 20. The stock is held below the head with its outer face in engagement with the guide 18. The edge of the pattern being held against said head and gradually turned by the operator following its own outline, the blades 71, revolving with the shaft cl, rapidly and accurately out said stock into the shape of said 5 pattern forming the sole H. To bevel one face of the sole, as shown at 25 in Fig. 4, the operator depresses the treadle 16, forcing the head. 0 outward and its blades on into engagement with the stock. Said head, being splined zoo onto the shaft, rotates therewith, and the cutting-edges 1) reduce the stock, forming said bevel in a manner readily understood by all conversant with such matters. By adjusting the blade 71 soles of different sizes may be cut from a single pattern D. By adjusting the cap B on the head 9 the depth of the bevel 25 may be gagcd. The knives m on the head a may be substituted by others having their cutting-edges practically at right angles to the shaft, said knives serving in this case to shave the face of the sole.

Having thus explained my invention, what I claim is- 1. A cutter-head for a sole-trimming machine,consistingof a cylindrical body g,having knives attached to one end thereof, and a peripheral pattern bearing adjacent to said end, an adjustable cap fitting over said body and provided at one end with a beveled guidingedge, and an adj tiStlllg-SCIOW passing through the opposite closed end of said cap and engaging the outer end of said body, substantially as set forth.

2. In a sole-trimming machine, the combination of two cutter-heads disposed adjacent to and facing each other on the same shaft, one of said cutter-heads being fixed to said shaft and provided with edge trimming knives, and the other cutter -head being splined to and longitudinally movable on said shaft, and provided with beveling or face entters consisting of elongated knives having angular cutting-blades adapted to ride over or encircle the fixed cutter-head, and means for shifting said splined head on said shaft to bring it into action.

In a sole-trimming machine, the combination of a bracket provided with lugs, a rotary shaft journaled in said bracket, a sliding cutter-head splined to said shaft, provided with cutters and a groove, a collar in said groove, a slide-rod disposed in said lugs and connected to said collar, an adjustable stop 011 said slide-rod, and a lever for actuating said slide-rod.
